Design Engineering DEI 10671 Vapor Block 3/8" Fuel Line Heat Shield Sleeve 36"

The Design Engineering Vapor Block fuel line sleeve is designed to protect fuel lines from radiant heat that can cause vapor lock and fuel system problems. This heat shield sleeve features a 3/8" inner diameter and 36" length, providing effective thermal protection for fuel lines in high-temperature engine compartments.

Key Features:

• 3/8" inner diameter fits standard fuel lines
• 36" length provides extensive coverage
• Reflects radiant heat away from fuel lines to prevent vapor lock
• Helps maintain consistent fuel pressure and engine performance
• Aluminized construction for maximum heat reflection
• Easy slip-on installation over existing fuel lines
• Withstands temperatures up to 500°F continuous, 2000°F radiant

Vapor Block sleeves are ideal for protecting rubber, braided stainless, or aluminum fuel lines routed near headers, exhaust manifolds, turbochargers, or other high-heat sources. By keeping fuel cooler, this sleeve helps prevent fuel vaporization, power loss, and hard starting conditions caused by excessive heat exposure.
